Recommended.
To connect agricultural machines to the coupling ball, it is required to extract pin 3 (fig-
ure 4.4.13), turn rest 2 in the horizontal direction, mount the coupling semi-sphere of the agri-
cultural machine onto ball 1, set rest 2 and pin 3 in the initial position.
On agreement with MTW, the customer is allowed to purchase the coupling ball manu-
factured by another company rather than "Walterscheid" and mount it onto the tractor, if the
parameters and coupling dimensions of this coupling ball comply with the parameters and
coupling dimensions set forth in Table 4.4.10.
ATTENTION: WHEN COUPLING TRAILERS, TRAILED MACHINES, SEMI-TRAILERS
AND SEMI-TRAILED MACHINES TO THE COUPLING BALL AS A PART OF DRAWBAR
HITCH, IT IS REQUIRED TO TAKE INTO ACCOUNT THAT PERMISSIBLE LOAD IN THE
HITCH POINT IN THE LONGITUDINAL DIRECTION SHALL CONSTITUTE NOT MORE
THAN 70.1 kN AND PERMISSIBLE VERTICAL LOAD IN THE HITCH POINT SHALL CON-
STITUTE NOT MORE THAN 20 kN (INDICATED ON THE LIFTING DEVICE SIDE MEM-
BERS), REGARDLESS OF THE VALUES INDICATED ON THE COUPLING BALL PLATE!
